To all whom t may conosci/z Be it known that l, Encan B. SYMoNs, a citizen of 'the United States, residing at Chicago, in the county of Cooliancl State of illinois, have invented a certain new and useful Improvement in Disks fot Crush.- ing-Machines, of 'which the following is a specification.

My invention relates to crushing disks for crushing machines and the like. lt is peu cnliai'ly applicable to disks to he used in crushing machines of Jdie rotary rocking disk type wherein the annular-chamber' foi'mecl liem'een a, 'pair cli inclined (lisks which rotate anl inoi'e one from the other to crush the material. These disks aire prei. eiabl'y made oinangganese steel or @they highliT resistanty niateiial which must lie easily machined anal it hccoines nccessaigfY in assembling tl erin the machine to nso sonic kind' o' paci-:ing4 'so prevent the expensive necessity ol Ii-inclini; lo mine them np.

ln my invention l' provicle means for holding this packing and means foi' holding the disk in posiion.

Other objects of invention will he parent from ille specification.
